I never heard back from iPD, which probably doesn't matter anyway. I took the MBC off yesterday. I notice that boost is about the same of may a bit higher--still about 13 psi.
Still no abnormalities. In fact, the car seems to be running great. I'm definitely going to need new tires!
I buttoned up everything. The chip kit comes with spacers to raise the foot rest (the plate the covers the ECU). They're needed because the kit harness sits on top of the ECU and is held in place with Velcro. The result is that you lose about an inch of leg room on the passenger side.
